My research has led me to this descent from Rollo
William Longsword
Richard 3rd Duke of Normandy
Richard 4th Duke of Normandy, Geoffrey, William Count Eu
From William Count Eu there were 4 sons
Robert Count Eu, William, Hugh and Ponts
Ponts had 4 sons, Richard, Osborn, Diogo or Dru, and Walter.
Richard Fitzpond had Simon, Walter and Richard.
Walter began calling himself Clifford and he has
Richard of Frampton, Rosamund, Lucy, Roger, Simon, Hugh, and Walter his heir. How does this measure up with what everyone has on the line?
